Yeah, the answer is A, can you please explain?? I got it wrong? I feel the ' to have been' was wrong

infinitive should always have the basic form of verb

Eliminating C & E --- because we need a be form after malaria
B --- redundant construction
In A & D -- Picking A (have been rather than having been) as this condition is not true anymore. Also, believed to is idiomatic than believed as.
Although A is not the ideal construction, it is the best among the available choices.
Hope this helps. I am terrible at explaining

"being" and "having been" are incorrect and A is the only one that is remotely correct.

I'm not a big fan of Princeton Review Verbal questions though.

A is correct here. The sentence is in passive voice construction, that's why to have been is correct.
And if u are considering C as an option, then Please not in C verb is missing and hence there is no SV pair in the 1st clause.

Original sentence is correct. ‘To have been’ is in sync with ‘has caused’
B. believed as being is awkward
C. Although Malaria doesn’t have a main verb. So, comma after malaria is wrong
D. believed as having been is incorrect
E. Contains same errors as B and C

First Split :

C : Although Malaria...................The recent excavation............ : ( removing the middle modifier, the stem reduces to ) : Does it make any sense ? = Eliminated

E : Although Malaria...................The recent excavation............ : ( removing the middle modifier, the stem reduces to ) : Does it make any sense ? = Eliminated

2nd Split :

A : ..............Malaria was believed to have been......................... introduced to X

B : ..............Malaria was believed as having been...................... inroduced to X

D : ..............Malaria was believed as having been.......................introduced to X

Believed To ........... SCORES OEVR..............Believed AS ; thus B / D Eliminated

leading to A = my take
